tional Year of the Child declared by the UN in 1979. In a first phase of the project, I obtained drawings of the six different building types treated in this book from more than 100 children aged 3-12 years in Turkey during a stay there as part of the faculty of Architecture of the Karadeniz Technical University in Trabzon under the auspices of the UN­ ESCO/UNDP program TUR/75/012. My special thanks go to Dr. Erdem Aksoy, then president of the university, and Dr. Ozgontil Aksoy, then dean of the faculty of Architecture and Civil Engineering, for their encouragement to carry out the project. I would also like to thank Dr. Kutzal Oztlirk, Sevinc Erttirk, Ali Ozbilen, Hasan Saltik, together with all the teachers in nursery and elementary schools in and around Trabzon who helped to collect the drawings.
